@GRAIPER ATTACHMENT FOR ROAD SGARIFIERS.

Application filed September 18, 1922. Serial: No. 686,826.

To all whom it may concern:

Be it known that l, WILLIAM T. BEATTY, a citizencof the UnitedStates,residin at Flossmoor, in the county of Cook and tabs of llllinois, haveinvented a certain new and useful Improvement in Scraper Attachments forRoad Scarifiers, of which the following is a specification.

This invention relates to conventional road scarifiers (see, forinstance, Figure 1 of the drawings, and Dewine Patent 1,030,- 287, June25, 1912) having a row of powerful tools or tines, usually verticallyadjustable, extending across the machine, adapted to loosen and tear upthe surface of an old roadway, preparatory to re-surfacing the same.

The objects of the invention are to provide such a machine with a roadscraping or leveling tool attachable to one or more of the scarifyingtines of the machine without interference with adjacent tines; topreferably but not necessarily adjust the scraper or leveling tool todifierent angular positions;'

to provide a cushion device for the scraper and-to provide an adjustabledepth gauge to "control the pressure of the scarlfier mechanism on thescraper.

'lhe invention consists in means for attaining the foregoing and otherobjects; which can be easily and cheaply made; which is satisfactory inuse and is not readily liable to get out of order. More particularly,the invention consists in specific mechanism for attaching the scrapingdevice to a given tine; for adjusting it in position with refer-- ancethereto and in many features and details of construction hereafter morefully set forth in the specification and claims.

Figure 9 is an end View at the point 9 of Figure 5.

Figure 10 shows means by which a scraper may be cushioned so as to allowit to follow irregularities in the road surface over which it travels. L

Figure 11 is identical with Figure 2 except as it illustrates the use ofsprlngs 64 in connection with the scrapers 34-36.

Figure 12 is identical with Figure 9 except as it illustrates the use ofsprings 64 in connection with scraper 56.

Figure 13 is identical with Figure 7 except as it illustrates the use ofsprings 64 below member 26 of Figure 7.

Figure 1 shows conventionally any sort of self-propelled road machine12, having a downwardly and rearwardly inclined power cylinder 14arranged to, under the control of the power fluid valve 16, reciprocatea piston rod 18 having at its lower end a cross-head 20, carrying by anysuitable means, as for instance a shaft 24, a plurality of tine grippingclamps26, extendin across I the road 22 to be scarified, firmly utdetachably holding generally vertically dispose-d tines 282930, havingsharpened points 31 adapted to enter and tear the road surface 22.

There are various reasons, well understood by those skilled in the art,why it is desirable to provide immediately adjacent to one or more'ofthe tines 28-30 a road scrapin or leveling device to move loose materiaon the surface of the road laterall thereof to one side or the other asmay be esired. For instance, if the road surface 22 has in it a welldefined rut, com rising a distinct depression 33 between a jacent ridges32, it is very often desirable not to scarify the entire road surfacebut to simply loosen the rid es 32 so that they can be scraped into theeression 33, at the same time loosening the bottom of the depression 33so that the meterial from ridges 32 which is moved into it will, inpacking down, take hold, so to speak, of the bottom of the de ression 30and become permanently attac ed thereto, a condition which will notoccur if depression 33 is not roughened. The conventional scarifierofFigure 1 is rendered adaptable for this particular kind of roadtreatment by lowering the particular tine, as 28, which it is thoughtmost desirable to have work in a particular road depression 33, whileleaving the other adjacent tines at normal height and above the roadsurface 22 and by detachably securing to this particular selected tine,as 28, an an ular scraper, as for instance 34, so verticafiy positionedthat as the machine of Figure 1 moves to the left, the win s or bladesof this scraper will gather the. ose materials from ridges 32 anddeposit them in rut depression 33. Figure 2 shows two such scrapers 34and 36 separated one from the other and each adapted to take care ofseparate ruts 33 which are to be treated ,by the machine. The scrapers34 and 36 may be placed on other tines 29 or 30 without departing fromthe invention.

When the times and scrapers have been adjusted, as shown in Figures 1and 3', the scrapers may, if desired, be held at a definitepredetermined position with reference to the main road surface 22 byadjustable depth gauges, the same comprising shoes 38, slidable over theroad surface and being selectively rigidly positioned on the ends ofshaft 24 by means of upwardly extending rods 40 passing through the endportions of the shaft and selectively securable in place by adjustableset screws 42. In the particular case here illustrated, the shoe 38 andthe rods 40 hapen to be made from a'single piece of a-n'guarly bentbar'material. The operator can 'by loosening the set screws 42 raise orlower the shaft 24 on rods 40 to thereby raise or lower the tines 28with reference to the ground 22. When, after making the adjustment, hetightens up the set screws 42, the shoes 38 prevent the lower ends ofthe tines entering the ground an amount more than the distancepredetermined by the fixed distance of the shoes 38 with reference tothe tines, and this prevents an undue pressure by the scarifier on thescraper or scrapers.

Each one of the scrapers 34 or 36 is detachably secured in differentselected vertical positions with reference to the time to.

which it is secured by some sort of a clampmg. device, that shown inFigure 6 being desirable. In this articular construction, the scrapercarries rigidly attached to it by any suitable means a block 44, havingthrough it a. vertically disposed tine receiving puassage 46 of greatersize than the tine 28, t 's passage being entered at its side by twovertically se arated set screws 48 and 50 by adjusting which theoperator can insure the scraper being substantially level with referenceto the ground-regardless of the particular angular position of the giventine to which it is attached. When, for any reason, it is desired to usea scraper which will travel over a wider space on the road than can beconveniently and safely carried by a single tine of the machine,atrian'gular scraper 50 of the type shown in Figure 4 may be provided,the same having at proper points tine gripping devices 52 and 54 adaptedto engage two previously selected separated tines in the row of tines282930. Scraper 50 is particularly desirable where the road 22 is moreor less crowned as shown' at 22* Fig. 8. The particular scraper 50 shownhappens to be designed to reach. from tine 28 to tine 28 but this isimmaterial. If, for any reason, the scrapers of Figures 3 and 4 do notfill the bill, a straight scraper 56 may be provided pivotally adustable by any suitable mechanism 58 to, preferably, but notnecessarily, tine 30 at or near the center of the machine. The ends ofthis scraper 56 may be braced with reference to the scarifier by braces60 provided with pivotal devices 62 for attachin them to certain tineson the row of tines, 1n the particulai case here illustrated only endtines 28,. These braces 60 are slidably adjustable through clamp 62 atsuitable points on the scraper 56. By suitably adjusting this scraper 56as to angular position and by raising the tines, as 29, not required forthe supporting of the scraper 56, to the position.

shown in Figure 9, the an 'ularly ad ustable scraper 58 may be attachedto the sca-rifying machine of the class described and the machine maytherefore be readily converted in:

to a plain road scraper notwithstanding the presence of the scarifyingtools.

Should there be any occasion, one or all of the scrapers 345056 may becushioned, as for instance by coiled springs 64 placed between thescraper and-the adjacent tine clamp 26 of the particular tine on whichthe scraper is mounted. In' such a case, the set screws 48 and 50 are ofcourse omitted or otherwiserendered inoperative to hold the particularscraper rigid in its adjacent particular tine. Under these conditions, astop 66 should be placed on the adjacent tine to prevent the scraperreciprocatin too far on the tine. This construction enab es theparticular scraper used to follow irregularities in the road surface 22in spite of the gauges In general operation, the operator first examinesthe road conditions to see what work is required and then selectivelyapplies the scrapers 34 and 36 (or either of them) or 50 or 56, makingthe adjustments shown 1n. the drawings and heretofore described inconnection with each of these diiferent F scrapers and then} proceeds tomanipulate the machine 12*to work uponthe road with the particularscraper selected.
